[0023] Specifically, the bolt carrier 2 is provided with a through hole for passing through the bolt, the opening diameter of the top of the through hole is larger than the bottom, and the head width of the bolt is larger than the diameter of the bottom opening of the through hole. The rod part of the bolt passes through the through hole of the bolt carrier 2, the bottom end of the rod part passes out of the bottom of the bolt carrier 2, and the head of the bolt cannot pass through the through hole of the bolt carrier 2.

[0024] As shown in the accompanying drawings, Figure 2 Bolt selection mechanism 3 includes plate body 31, blanking hole 32 and power cylinder one 33, the piston rod of power cylinder one 33 is fixed on plate body 31, plate body 31 is provided with a plurality of blanking holes 32, and the plurality of blanking holes 32 are connected with a plurality of bolt containers through a plurality of hoses respectively.

[0025] First, the rotating table 1 rotates the bolt carrier 2 loaded with bolts to below the plate body 31, and then the power cylinder 33 drives the plate body 31 to move horizontally until a certain discharge hole 32 on the plate body 31 moves directly below the bolt carrier 2, so that the bolt container connected to the discharge hole 32 drops a certain type of bolt into the bolt carrier 2. By aligning different discharge holes 32 with the bolt carrier 2, different types of bolts can be fed into the bolt carrier 2.

[0026] The glue discharging mechanism 4 includes a transparent glue barrel 41, an optical fiber sensor, a flow sensor 42, and a glue valve 43. The transparent glue barrel 41 is provided with an optical fiber sensor on one side for detecting whether the glue level in the transparent glue barrel 41 is below a set value. The transparent glue barrel 41 is connected to the glue valve 43 through a hose, and the hose between the transparent glue barrel 41 and the glue valve 43 is provided with a flow sensor 42.

[0027] The glue in the transparent glue barrel 41 provides glue for the glue valve 43, and the glue pump extrudes the glue in the transparent glue barrel 41 through the glue valve 43. When the glue level in the transparent glue barrel 41 is below the position of the optical fiber sensor, the optical fiber sensor will transmit a signal to the PLC, and the PLC will remind the staff through the alarm that the glue needs to be replenished. The flow sensor 42 can transmit the glue flow information to the PLC.

[0031] When the rotating table 1 drives the bolt carrier 2 to rotate the bolt between the support column 61 and the chuck 63, the support column lifting cylinder 62 drives the support column 61 to move upward, the support column 61 pushes the bolt upward, at this time the bottom end of the shank of the bolt is placed in the groove on the top of the support column 61, until the head of the bolt is pressed in the chuck 63, so that the bolt is clamped between the support column 61 and the chuck 63.

Then the bolt rotating mechanism 6 starts to rotate after the bolt is pushed to the gluing position, and the glue valve moving mechanism 5 drives the discharging end of the glue valve 43 to move to the shank of the bolt, while the bolt rotates, the glue valve 43 moves up and down to glue the shank of the bolt. During the process of rotating and gluing the bolt, the CCD camera 7 on one side transmits the image of the bolt to the PLC, and the PLC judges whether the bolt is qualified. If the bolt is not qualified, the bolt is rotated to the waste taking position, the bolt is taken out from the bolt carrier 2 by the multi-axis manipulator with suction cups, and then the bolt is placed in the waste collecting mechanism 8. If the bolt is qualified, the bolt is rotated to the qualified product taking position.
